PROBLEM: The endothelial glycocalyx (EGX) plays an important role in vascular integrity. Recently, increased levels of EGX components were detected in the circulating blood of healthy pregnant women and were related to the increased tendency to edema formation during gestation. However, the EGX has not yet been systematically studied in non-pregnant women during ovulatory cycles. METHOD OF STUDY: Serum levels of EGX components syndecan-1, heparan sulfate, and hyaluronan in healthy women (n = 16) at 3 phases of the ovulatory cycle (early follicular phase, at ovulation, and mid-luteal phase) were compared with a control group of healthy men (n = 10)...

PROBLEM: Salmonella Typhimurium (S. Tm) infection in pregnant mice results in massive placental infection, fetal loss, and exacerbated systemic infection. The Th17 host response can aid control of S. Tm infection, whereas successful pregnancy correlates to a dampened inflammatory and enhanced regulatory T-cell (Treg) response. METHOD OF STUDY: Mice were infected systemically with S. Tm and tissue bacterial burden, splenic Th17 and Treg cell numbers, and serum cytokines were analyzed...

PROBLEM: The mechanisms underlying the regulation of decidual natural killer cells (dNKs) at the maternal-fetal interface are unclear. METHOD OF STUDY: Primary trophoblasts (TROs), decidual stromal cells (DSCs), and dNKs were cocultured, and responses to LAIR-2 (LAIR-1 inhibitor) and P4H shRNA (collagen inhibitor) were studied. RESULTS: Coculture of dNKs with primary TROs/DSCs resulted in downregulation of Th1 cytokine production by dNKs. These effects were abrogated by LAIR-2 and P4H shRNA...

PROBLEM: Differences in circulating (peripheral) and mucosal T-cell phenotypes in chlamydia-infected women remain largely unknown. METHOD OF STUDY: Thirteen paired mononuclear cell specimens from blood and cervicovaginal lavages collected from chlamydia-infected women were stained and analyzed using ten-color cell surface flow cytometry for T-cell distribution, activation status, homing, and T helper (Th)-associated chemokine receptors (CKRs). RESULTS: A higher proportion of genital mucosal T-cells were activated (CD38(+) HLA-DR(+) ) and expressed CCR5 and Th1-associated CKR CXCR3(+) CCR5(+) compared to peripheral T-cells, but a lower proportion of mucosal T-cells expressed homing CKR CCR7, Th-2 associated CKR CCR4, and CXCR3(+) CCR4(+) for both T-cell subsets...

PROBLEM: Effective therapy for endometrial receptivity of patients with repeated embryo implantation failure (RIF) is far undeveloped. Whether intrauterine perfusion of dexamethasone (DXM), local administration of drugs with less systematic side-effects, benefit for embryo implantation by suppressing uterine NK (uNK) cells to improve endometrial receptivity remains unknown. METHOD OF STUDY: Women with RIF were analyzed for the correlation between the percentage of uNK cells during implantation window and following clinical pregnancy rate to determine the appropriate range of uNK for embryo implantation...

PROBLEM: In endocervical epithelial cells (End1/E6E7), miRNA let-7f plays an important role in the control of innate immunity. The underlying molecular mechanism for let-7f regulation in these cells remains largely unclear. METHODS OF STUDY: let-7f was knocked down in End1/E6E7 cells using siRNA, and differential gene expression was analyzed by microarray. Differentially expressed genes were validated by qPCR and Western blot. Expression of let-7f was studied by qPCR after inhibition of C/EBPβ with betulinic acid (BA) and pCMVβ plasmid and after overexpression of C/EBPβ with pCMVβ+ plasmid...

PROBLEM: The role of extracellular signal-regulated kinase (ERK)1/2-mediated angiogenesis during endometriotic nidation is unknown. We posit that ERK1/2-induced angioblast differentiation and proliferation promotes ectopic endometrial angiogenesis. METHODS OF STUDY: Human eutopic and ectopic endometria were immunostained for total- (T-) or phosphorylated- (P-) ERK1/2 or double-immunostained for P-ERK1/2-CD34 and PCNA-CD34. Estradiol (E2 ), cytokines, normal peritoneal fluid (NPF) or endometriotic peritoneal fluid (EPF) ±PD98059, an ERK1/2 inhibitor, treaded primary human endometrial endothelial cells (HEECs) were evaluated by T-/P-ERK1/2 immunoblotting, MTT viability and tube formation assays...

REVIEW
Arsenio Spinillo, Fausta Beneventi, Roberto Caporali, Veronique Ramoni, Carlomaurizio Montecucco
Undifferentiated connective tissue diseases (UCTDs) are a heterogeneous group of disorders characterized by symptoms and signs suggestive of systemic autoimmune rheumatic disease (ARD), but which do not fulfill all the established criteria for definite diagnosis of a condition. Although a third of UCTDs can progress to a definite ARD within months or years, most UCTDs can remain stable for years with minimal disease activity. The annual incidence of UCTD in the general population ranges from 14 to 140 per 100 000 people...

PROBLEM: Chlamydia trachomatis infection is the most common sexually transmitted bacterial infection worldwide and known to increase the risk for HIV acquisition. Few studies have investigated how infection of epithelial cells compromises barrier integrity and antimicrobial response. METHOD OF STUDY: ECC-1 cells, a human uterine epithelial cell line, were treated with live and heat-killed C. trachomatis. Epithelial barrier integrity measured as transepithelial resistance (TER), chemokines antimicrobial levels, and antimicrobial mRNA expression was measured by ELISA and Real-time RT-PCR...

PROBLEM: In molecular analysis of tissue biopsy specimens, one crucial aspect is characterization of immune cell populations. This is especially important for evaluation of uterine receptivity by assessing levels of lymphocyte populations including CD56(bright) CD16- uterine NK cells and CD56(dim) CD16+ conventional NK cells. Our objective was to investigate whether measuring total RNA transcripts from a tissue specimen would accurately reflect immune cell levels and be a new technique to assess immune cell subsets...
